After transitioning from the clicking function Tinder initially used, Tinder became the first "swipe app", now a term to describe various apps that use swiping left or right to control what content the user sees in a browsing fashion.
Companion apps were being developed by different companies allowing users to, for example, use the user's heart rate to determine which direction to swipe instead of the user swiping with their hands.
The app is used as a dating app or hookup app, depending on the user's individual preference.
Information available to the users is based on pictures from Facebook, a short bio that users write themselves, along with linking Instagram and Spotify account.
As of October 2014, the app was processing over one billion swipes per day, producing about twelve million matches per day.
